Imatest Master

Test everything from sharpness and distortion to color and illumination with Imatest Master.

2020.1 Features and Enhancements:

Lighting Control — Set up and control DMX lights (Kino Flo) and Lightboxes, and monitor lighting conditions with an Isolight puck. The feature lets you manage the brightness and color temperature of individual lights and save your settings to scenes that allow you to perform rapid switching between light configurations.

Shannon Information Capacity — Measure the Shannon information capacity of imaging systems in units of bits per pixel from sinusoidal Siemens star patterns. Because frequency-dependent signal and noise are measured from the same locations on the star, they are subject to identical image processing unlike slanted-edge MTF and flat patch-based noise measurements.

New CCM Linearization Option — Calculate the linearization parameters from the grayscale patches on the target. Results are more accurate than previous methods. (The previous Color Correction Matrix [CCM] calculation, derived from images of color charts [including grayscales], generally required knowledge of the gamma [Opto-Electric Conversion Function] curve of the image for proper linearization.)

Software Analytics — This helps us understand the usage patterns of license holders. When you opt in to share usage data with us, we can learn which areas of the software are used most often, which will help us improve our support and offer new licensing options.

5.2 Features and Enhancements:

ON Semiconductor DevwareX support for this advanced image sensor interface software, which replaces Devware. Support for the APbase image acquisition API.

Decompanding for the proper processing of piecewise linear (PWL) companded RAW files, which can extend sensor dynamic range by allowing different tonal curves for ranges of digital output values.

Contrast Detection Probability (CDP) from Contrast Resolution chart using low-contrast path triplets to calculate the draft IEEE P2020 metric. CDP is a metric for the distinguishability from two input light levels through an imaging system.

Dynamic Range (DR) Output Resistance to Flare Light – We can now detect conditions where flare light causes exaggerated DR measurements and can remedy the misleading measurements by limiting the quality-based DR to the slope based DR, which is defined by the scene density where the patch pixel-level stops decreasing.

Improved distortion calculation: Checkerboard and SFRplus modules support an enhanced set of distortion models, and provide faster and more accurate distortion coefficient and center of distortion estimations.
